Otago is a region of New Zealand in the south of the South Island administered by the Otago Regional Council. It has an area of approximately 32,000 square kilometres (12,000 sq mi), making it the country's third largest local government region. The name "Otago" is an old Māori southern dialect word (the North Island dialect equivalent is "Otakou"), introduced to the south by Europeans in the 1840s. The exact meaning of the term is disputed, with common translations being "isolated village" and "place of red earth", the latter referring to the reddish-ochre clay which is common in the area around Dunedin. Otago is also the old name of the European settlement on the Otago Harbour, established by the Weller Brothers in 1831, which lies close to the modern harbourside community of Otakou. The place later became the focus of the Otago Association, an offshoot of the Free Church of Scotland, notable for its high-minded adoption of the principle that ordinary people, not the landowner, should choose the ministers.
